A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and ...

Discover how astronomers use stellar parallax to navigate spacecraft in deep space without relying on Earth-based beacons.

The two sets of images were compared, showing definite parallax. According to NASA, this is not only the first time a spacecraft has measured stellar parallax, it is also the longest measuring ...

The article details the historical significance of observing double stars, highlighting their use as visual acuity tests in ancient Arabic texts and their role in advancing our understanding of ...

(Nanowerk News) In 1838, Friedrich Wilhelm Bessel won the race to measure the first distance to a star other than our Sun via the trigonometric parallax – setting the first scale of the Universe.

As NASA's New Horizons spacecraft traveled through the Kuiper Belt at a distance of 438 million miles from Earth, an international team of astronomers used the far-flung probe to conduct an ...

Queen guitarist (and astrophysicist) Brian May, a member of the New Horizons science team, uses his patented OWL viewer to check out the stereo images of Proxima Centauri that he created by combining ...

For most of us, the countless bright spots in the nighttime sky all seem to be stars. But in fact, some of those spots are actually planets, or distant suns, or even entire galaxies located billions ...
